#是特殊字符
主要是保留字
33是数字

推荐答案

您需要开发一种语言的扫描仪，对吗?
如果上述任务不是家庭作业，请查看 flex [手动"实施扫描仪...).
:)

You need to develop a scanner for a language, don''t you?
If the above task is not homework, then have a look at flex[^], it may help you a lot (if it is homework, I suppose you need to ''manually'' implement the scanner...).
:)
